From excerpt on photo: S.B. Batdorf, above, instructor in advanced mathematics, is shown discussing with Manuel Stein the installation of strain gages on a test specimen installed in the NACA combined testing machine, located in the Structures Research laboratory, from which test data may be obtained by tension and compression, twisting, bending in two directions, and shearing in two directions. Stein is working towards his master of aeronautical engineering degree in the graduate program in the Department of Engineering of the University of Virginia. He intends to use data obtained from tests made with this machine in writing the thesis required for a master's degree.
